Online monitoring device for power reactor vibration

Abstract

The invention provides an online monitoring device for power reactor vibration. The device includes a monitoring parameter sensor used for monitoring vibration and voltage and current signals of the power reactor in a work state; a signal processing module used for receiving signals monitored by the monitoring parameter sensor and performing amplification, filtering and synchronous digital-analog conversion processing after performing synchronous acquisition on the signals; a signal data reading module used for real-time reading of vibration and voltage and current signals which undergo the amplification, filtering and synchronous digital-analog conversion processing; a GSM data communication module used for monitoring information, which is read by the signal data reading module in a real-time manner, and forming vibration waveforms and current and voltage waveforms through the information for transmission so as to perform map display and data analysis; and an analysis display and alarm module used for obtaining waveform data of the vibration and waveform data of the current and voltage from the GSM data communication module for rapid anti-aliasing Fourier transform processing and continuous real-time display.

Description

technical field [0001] The invention relates to an on-line vibration monitoring device for a power reactor. Background technique [0002] With the rapid development of our country's economy and the improvement of people's living standards, the scale of the power grid is gradually expanding, and the power load is increasing rapidly. The requirements for power quality are getting higher and higher. The reactor is an important part of the power reactive power compensation complete set, which can compensate the capacitive effect of the long line, limit the voltage rise, maintain the reactive power balance, and play an important role in improving the power supply efficiency of the power grid, improving the voltage quality, and reducing the loss of the power grid. When in use, it is generally a group power reactor switching operation. [0003] Power reactor is an important equipment to ensure the voltage quality of users. Once a failure occurs, it will have a great impact on the ...

Problems solved by technology

The severe vibration of the reactor not only affects the voltage quality, is not conducive to loss reduction and efficiency increase, but also generates excessive noise

If the reactor group is forced to continue to operate under the condition of severe vibration, it will not only affect the safe production of the power system, cause equipment loss, but also greatly damage the life of surrounding buildings, endangering the production and operation environment
